西德的亚琛大学与美国的犹他大学合作用了6年多时间研制出一种Heimes便携式人工心脏驱动器。这个装置的设计思想是用一个小型,轻便、自适应的装置来替代笨重的压缩空气驱动系统。该装置的基本结构是一个由电机驱动的园形螺杆/活塞组合件,这个电机能量转换装置结构紧凑,效率较高。工作参数为:心输出量2～11升/分;驱动频率50～130次/分; Aachen University in West Germany and the United States Utah University spent more than six years to develop a Heimes portable artificial heart drive. The design idea of ​​this device is to replace bulky compressed air drive system with a small, lightweight and adaptive device. The basic structure of the device is a motor driven circular screw / piston assembly, the motor energy conversion device is compact and efficient. Working parameters: cardiac output 2 ~ 11 liters / min; drive frequency 50 ~ 130 times / min;
